NEW ORLEANS — LaMichael James was a speedy running back in the University of Oregon's fast-paced offense under new Philadelphia Eagles coach Chip Kelly. That combination of fleet feet and rapid thinking has helped the rookie be a quick study with the San Francisco 49ers' offense.

"It's pretty much similar," James said in comparing what's done in San Francisco to what the Ducks do in Eugene. "You are in the (shot)gun and it is pretty much a zone-read offense. It has been doing a great job helping me out being a young player and doing some stuff I am familiar with."

It hasn't taken long for James—who wasn't a factor for much of the season when second-year change-of-pace back Kendall Hunter was healthy—to get up to speed down the stretch and in the playoffs. After rushing for a key touchdown against the Atlanta Falcons in the NFC championship game, you can bet James will be on the Baltimore Ravens defense's radar Sunday in Super Bowl XLVII.

The 49ers are blessed with many sudden and explosive athletes, from quarterback Colin Kaepernick to tight end Vernon Davis. They also have a most venerable speedster in future Hall of Fame wide receiver Randy Moss. James has good reason to think he might be faster than all of them.

"Probably long speed; I do not know about (40-yard dash-)wise," James said. "I would have to race some guys and see. If I say that, then everybody will try to race me after practice one day. I will tell you Sunday after the game."

As long as James helps the 49ers run past the Ravens, his teammates shouldn't mind losing to him.
